Zo all 'whom z't may concern:l

Be it known that I, JOSEPH S. Wnmmius, a citizen of the United States, residing at Riverton, Burlington county, State of New Jersey, have invented a new and useful Resilient Cushioning Wheel E uipment, of

which the following is a speci cation.

My invention further consists of a novel construction of a transversely disposed core which is formed in such a manner as to provide for the uniform distribution of the duid, so that thecore's will have definite degrees of compressibility, both circumferentially and transversely.

' It further consists of otherv novel features of construction all as will be hereinafter Y fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same hasbeen found in practice to give satisfactory and reliable results, although it is to be Iunderstood that the various instrumentalities of which m invention consists can be variously arrange and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figures 1 to 8 inclusive represent transverse cross-sections of tires, rims, and mechanisms for uniting them, embodying my invention. v

Similar numerals of reference indicate corresponding parts in the figures. v

Referring to the drawings Referring Iirst to Figs. 1 and 2, 15 designates a rim provided with a facing 16 u on which a transversely divided annulus 1 is sprung by expansion `so that the facing 16 is seated in an annular groove 18 between shoulders 19. 20 designates the outer tire casin circumferentially split at 21, and provide with annular ribs or terminals 22 seated in corresponding grooves 23 ofthe annulus 17, and supported and sti'ened by reinforcing strips 24. 25 designates a tread of any desired nature, which is reinforced by strips of ber or other material 26, prefer .ably located as illustrated. The cushioning core is adapted to receive compressible iuid, and is provided with a solid portion having ribs, ridges or projections capable of carrying the load in case of relapse of the inner tube, 27, it being understood'that all ofthe constructions illustrated are designed to be provided with means for ination, one type of such means being shown in Fig; 4.

28 designates the solid cushion having annular ribs, such cushion being shown in Fig. 1 on the inner periphery of the inner tube 27, While in Fig. 2 the same is shown at the outer periphery, and the inner periphery of the spacement within the inner tube is provided with transverse ribs 29, and thev construction seen'in Fig. 2 may be employed either vwith or without Huid pressure in the inner tube. The outer casing'20 in Fig. 2, is provided with terminal flanges 30 preferably having reinforcements- 3l and supported by a removable annular seating and rim member 32. The parts are held in place by interlocking clamping rings 433 and 34, one of which is provided with an annular rib 35 interlocking with the corresponding depres sion in the tire facing 36 of the rim 15.

37 designatesradial bolts. The valve illustrated in Fig. 4 comprises an outer member 38 adapted to remain with the tire part and carries a check valve, and also an inner valve member 39 detachable from the member 38. The lining 27 in Fig. 4 may be an inner tube or represent the inner portion of a core whose remaining parts 40 areV not shown in detail, and if such was used it yvould preferably be provided with stifenlng and strengthening materialy in a similar manner .to the core 32 seen in Fig. 2. If an The outer casing has abutments 45 com los pressed together initially before the locking mechanism is applied.

In the embodiment seen in Fig. 6, the rrm is shown with an annular channel 46, within which a split ring 47 is compressed, after 1t has been placed on the tire 48 so that the reinforced portions 49 are secured within the interlocking recesses 50. The lips 51 of the ring 47 are of greater diameter than the reinforcing strips 52 in order to provide greater stability and prevent dislodgment due to cutting or stretching.

53 designates cavities for lightening the construction and increasing resiliency. The tire 48 may be a single tube or may loesplit at one or more points as at 54, with inserts to complete the construction and form support for the compressible members 55 and 56, and the space 57 may receive Huid under pressure, if desired, and either of the members 55 or 56 may be omitted if desired.

In the embodiment seen in F ig. 7, 58 designates clamping members having fastening devices 59, which clamp a terminal 60 in position, such terminals being reinforced at 61, and adapted to interlock with the clamping members so that such terminals are compressed against an intermediate annular support 62, which receives the pressure transmitted from the tread portion 63. 64 designates reinforcing layers of fabric. The cushion core in this embodiment, comprises a plurality of layers of annular ribs 65, interspersed by transverse ribs 66, passages 67 being provided between them to provide for the free passage of fluid. These layers may be independent or united and as shown I employ two oppositely facing strips each having circumferential ribs on one side and transverse ribs on the other, the transverse ribs being placed toward each other and having placed between these two strips a third strip, having both sides formed with annular ribs.

In the embodiment seen in Fig. 8, the rim construction differs from the Marsh type, in that the rim member 43 terminates laterally in a glitter 68 coperating with a locking ring 69, and also in the fact that the annular rings 42 are initially compressed before the locking mechanism is put in use against the terminals 60 and the supporting edges 70 of the rings 42 are extended to form a broader seat and support for the tire.

71 designates a filler and core between the tire terminals, which is prevented from creeping by means of bolts 72, and the compression of the terminals against such core. The. cushion core employed comprises upper uml lower circumferential ribs 28, with intermedialely oppositely placed transverse ribs- 73. which vary in depth from their edges to :ln-ir highest points at the center. l `luiil pressure is preferably employed in this type which may have Y free passage through the apertured body portion of the ribs 73.

The spacements or apertured parts of the different types of cushion cores shown, can be filled with any suitable gas, fluid, viscous or mobile material, or with a material whlch will solidify after insertion in the core and provide the requisite elasticity and mobility, and any desired pressure may be employed.

It will be seen that, with the exception of the spacement or channels 5,7 seen in Fig. 6, the Huid in all the embodiments shown has free communication, and the air is not trapped locally as in my co-pending application, led December 8th, 1909, Serial No. 532,045. In all the embodiments of my invention, the inner portion of the wheel equipment is circumferentially inextensible., and the fabric or other reinforcements eX- terior of the cushion core render such portion circumferentially inextensible, so that the cushion core is located between two circumferentially ineXtensible fields.

It will be seen that the outer casing has a tension belt crossing vertical planes of the construction outwardly of the major transverse axis of the construction with flattened arch formationsubstantially throughout the width of the tread bearing surface with curvatures at the sides to terminal seatings.

he core is in constant supporting relationship withthe inner walls of the casing and has an annularly and transversely arranged channel in which is located a cellular construction. The annular body, inwardly of the core space, is provided with means to secure circumferential vinextensibility and means are provided to secure the core and casing in constant coperative relationship.

It will now be apparent that I have devised a novel and useful construction of a resilient cushioning wheel equipment which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described preferred embodiments thereof which in practice will give satisfactory and reliable results, it is to be understood that the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
